Working Principles

The TC74VCX125FTEL is designed using low voltage, high-speed CMOS technology. It operates as a quad bus buffer gate with 3-state outputs. The device acts as a level shifter, allowing bidirectional communication between devices operating at different voltage levels. When the output enable (OE) pin is active, the input signals are passed through to the corresponding output pins. When the OE pin is inactive, the outputs are in a high-impedance state.

Detailed Application Field Plans

The TC74VCX125FTEL can be used in various applications, including but not limited to: 1. Interface conversion between microcontrollers and peripherals operating at different voltage levels. 2. Level shifting in battery-powered devices where low power consumption is crucial. 3. Communication between sensors and microcontrollers in IoT applications. 4. Signal buffering in data acquisition systems. 5. Voltage translation in automotive electronics.
